Abstract
A system is disclosed for generating a time scale modification of a digital waveform. A digital waveform provider produces an input digital waveform at a first time resolution, the digital waveform being a sequence of overlapping speech segment windows. A time-domain time scale modification process overlap adds selected windows from the input digital waveform to create an output digital waveform representing a time scale modification of the input digital waveform. The process operates at a second time resolution lower than the first time resolution to determine the relative positions between adjacent windows in the output digital waveform.
